Detailed Description

A class for setting a virtual sensor link.

This class is used to initialize the forward and backward phase of Newton-Euler's method in the Inverse formulation, but also to have estimation of the FT measures by the sensor; the sensor frame is defined with respect to the i-th link, where the sensor is attached. Note that this is a virtual link, since there's no iDynLink attached: it is just necessary to make the recursive Inverse Newton-Euler computations; however, inertia, mass and COM are defined, for the portion of link defined between sensor and i-th frame.
